Abstract

Use of resistive sheet boundary condition in the finite-difference time-domain (FDTD) analysis of scattering problems involving resistively coated dielectric object is described. The algorithm is introduced through an analysis of E-polarized scattering from a thin resistive strip. For the sheet resistance R =ƞ Z0/2 with Z0 being the intrinsic impedance of vacuum, numerical experiments indicate that algorithm stability is ensured in all cases if δt is chosen according to cƞδt ≤δ. Validity of the resultant FDTD method is verified in a comparison of computed E-polarized scattering data for several resistive strips with existing data. New results on the E-polarized scattering behavior of resistively coated dielectric strip as a function of surface resistances and angle of incidence are also presented. Finally, extension to the H-polarized case and application of the present method to pulsed problems are briefly discussed.
